如何在遊俠預覽中啟用語法突出顯示？

我看過一些截圖，其中游俠在其預覽視窗中使用語法高亮。所以我想知道如何啟用此功能，發現我需要scope.sh目錄中的文件， 該文件/home/user/.config/ranger/scop.sh將使用命令生成 $ ranger --copy-config=scope。然而，在生成它之後，預覽視窗完全消失了，儘管我插入set use_preview_script true了rc.config.

問：有人知道如何在 Ranger 預覽視窗中啟用語法高亮（尤其是 C/C++）嗎？

$ sudo apt install highlight

然後重新打開ranger。

Ranger 支持，highlight詳見http://www.andre-simon.de/doku/highlight/en/highlight.php

通過執行在macOS上安裝brew install highlight. 可用主題列表如下： highlight/<highlight_version>/share/highlight/themes例如：

Ranger 在scope.sh. 要使用特定主題，HIGHLIGHT_STYLE應設置變數，例如：export HIGHLIGHT_STYLE=clarity
